It's Fun to Play the Piano ... Please Pass It On!

I saw your guitars, cool, but I would not want to have them hanging around my neck for more than a set.

The trend in all things is smaller and more efficient, pianos included I hope.

Even though things don't evolve as fast in the piano manufacturing business as in others, the next better piano will be lighter, more stable and reliable. I don't see where granite would contribute to this goal.

Marty, you have no case, you speak from a wood perspective which has no relation to using granite as a bridge, the properties of these materials are of the opposite to each other. you would know this if you understood the concept before being rude yourself. don't expect me to argue with you when you no different than the sensitive types in here in agree with your lack of information just because you have experience.. read below..

All 23 prototypes weigh less than the stock weight, another thing you assumed? right? did you ask me? no again, so your sarcasm warrants a similar response but I know better.

The guitars speak faster than any other and so on.. this will take time to implement because folks aren't aware how this Stonetone┬« concept fits.

I will converse with you folks but won't take your sarcasm or quick judgments when you base your opinions on pure assumptions especially since you haven't played one or have knowledge of the attributes using granite as a transducer within any stringed instrument.

Thank you Jean.

Robert your ego is amazing. Your sounding more and more like a cheap date that can't handle a compliment. You may have stumbled over something interesting; letting that go to your head spells disaster for both you and the product your associated with.

If there is anything of interest here, it's the stone bridge not you.

I have not commented on your product. Wood carrying vibrations is a transmitter, not a transducer. Your usage is incorrect. You are rude, insulting, and beligerent. That, you have proved beyond a doubt.

I have not heard the term "Smarty Marty" since I was in early grade school. Your need to resort to using it indicates your level of social development.

Have a lovely life as you do your best to promote your product in such a fine and skilled manner.

Marty, Mark etc, have no findings or test results of granite being used for a piano bridge because there is no patents ever mentioned having any details in the abstract of a patent.

Seems that the disrespect started with your continual slams.. and yet you keep coming back for more, how dumb are you? relaxe and try to digest what is the NEW technology to understand, like it or not, it is real.

Some folks who feel they have to slam another to make themselves feel better. Transducers folks have several meanings depending on the application in my invention it has a couple of terms based on the instrument.

Bob newbie I am new to this forum but sounds like your familiar of the rhetoric from certain people who enjoy being crass and opinionated before seaching the facts first.

These few people are the minority and lacking at that. The validity of this invention is fact no matter what the sensitive types think.

This topic was moving fine until MarkR started his crass disrespectful attitude than be a PROFESSIONAL. read below and from that point on the rhetoric never stopped since I posted comments from 2 professional pianist Kary who played the piano @ 444htz along with Dr. Richard Bosworth had comments. so don't come in here with your insults or muffled garble. It is senceless and a waste of everyones time to read your opinionated untruths.

MARK R so called professional response to my previous post of Kary and Richard. You contradict yourself by saying in all due respect then you end with downright gobbledygook. Your a joke Mark.

What I find really strange in this thread, and with all due respect, very detrimental to a discussion of the technical merits of the granite bridge, is an apparently random mixture of... science (e.g. transducer principles, partial envelope),... pseudo-science (utilizing "stored energy of atoms in a crystalline matrix" for a faster response),... new-age mysticism (chakras and healing frequencies being felt at cellular level) and... downright gobbledygook.

Any more questions of the invention or how and why it works? talk to one of your own & email (www.richardbosworth.org) and see how he responds to your crass untruths. manufacturers don't listen to the techs, they listen to the performer when ultimately there opinion is the one that sells pianos not the other way around. I am continuing my work on the 9' 1965 SD Baldwin concert grand today.. Have a great day.

Robert, don't underestimate the influence of techs on potential customers. We are the people who regularly visit, tune and work on these instruments and we often discuss pianos and their performance envelope with them. Many non-techs come to this forum to munch popcorn and read up on our musings also. Take a look at some novel changes of pianos over the years and you will undoubtedly find technician testimonials beside them in the advertising/promotions.

If I buy a car, the first thing I do is go to mechanics forums and read up what they have to say about them, very few people are in a better position to criticise a product from a technical/professional perspective than the ones who work, rebuild or service them. At this somewhat early stage of this new bridge, I would think you would embrace input or constructive criticism to possibly get the final polish/shine on the product.

Let it be noted, Robert, that you decided to post about your new invention in a forum for piano technicians, who as a whole are certain vastly more knowledgeable about the piano and how it works than Richard Bosworth or Thomas Zoells (who I know personally - he's a great guy and runs a fantastic organization in Pianoforte, but he's simply not going to be able to answer detailed technical questions authoritatively).

I had a feeling you wouldn't be able to take any constructive criticism, or any suggestions to tone down your responses. It's a shame. Your negativity certainly isn't hurting any of us, and if anything is only dissuading others from taking you and your product seriously.

I watched the video..comparing a 6ft piano to a 5ft1" is comparing apples to oranges?they should be of equal length..the bass is dead in the 5' piano which creates an unbalanced loudness in the treble side, though the sustain is nice..

You still looking for that black spec on your little white piece of paper? Don't bother me with your Babble. You and several others have no contributing dialogue to this topic and yet you still come back...

Seems you would be better as a english major since you aren't talking about pianos which this forum is used for. I have never attacked anyone one in this forum other than pointing out the folks that speak from emotion than fact which the naysayers who have posted garble have already identified themselves as such.

Stonetone┬« is here to discuss certain findings and talk to anyone interested in this concept than fuss with folks like you who babble about non related issues.

Hi RobertI keep wondering: Why not use glass instead of granite? Glass should have similar bridge mass and transmission properties that is the essence of your approach, but should:1) Be easier and cheaper to fabricate.2) Less chance of microfractures and microfissures (a concern with some posters).3) The homogeneity of glass should reduce the possibility of random refraction of sound waves as it passes though the various densities of mineral components within granite. i.e. sound waves should be less distorted as they pass through glass rather than granite.

2) Piling on more insults and using emotion as an excuse do nothing for your 'scientific' case.

As for the relevance of my posts, you'd know better if you bothered getting a feel for this forum before pitching your sideshow. After your silly and insulting first response to my reasonable inquiries, I gave up on you. And, after sitting back and watching you insult experts, professionals, and enthusiasts here alike, it seems to me you need a boost getting off your high horse. You want to come across as credible and rational? Express yourself accurately and properly, and treat your audience with respect.

Another piece of advice: Any data or proof has to be logically presented and intelligible. Poorly recorded videos on YouTube of crappy pianos recorded from different perspectives only proves you aren't meticulous or properly prepared, which speaks directly to your lack of credibility.
